Evolution is progressive

One of the much common misconceptions, with a history big ahead Darwin, is that evolution is draw nearive; that things fare more coordination compound and perfective in some way.

Recently, the manage has resurfaced, shorn of the mysticism of earlier debates. life scientist J.T. Bonner argued that there was a rise in complexness of organisms everyplace the long term [1988], and others were arguing for a form of topical anaesthetic progress under the terms arms race [Dawkins and Krebs 1979] and escalation [Vermeij 1987].

Gould [1989] felt so strongly about it he was moved to deny that, at least since the Welsh explosion, there has been any progress at all. Much of the modern debate centres on what counts as progress. Gould [1996] thinks that the apparent trend to complexity is just a matter of random evolution that started at a minimal ! wall of complexity: Others [cf Nitecki 1988] claim that there is superstar progress because any increase over zero is a net increase, and that different measures will give different...
